Cant get "selected" to work when looping through months and dates

I have this code that outputs select lists of months and select lists of the dates (1-31)

The form loads OK and the months and dates are in the lists just fine.

But when I select a month and a date I want it to stay selected when I submit the form

So if I choose May 5 and click submit

I want it to look like this

But no matter what I select it always ends up January and 1

Here is the code

<tr>

            <th>Choose  Feed Date:</th>

            <th align="left"> <select name="feed_date_m">

                <cfloop index="m" from=1 to=12>

                  <option value="#m#" <cfif #form.feed_date_m# is "m">selected</cfif>>#monthasstring(m)#  </option>

                </cfloop>

              </select>

              <select name="feed_date_d">

                <cfloop index="d" from=1 to=31>

                  <option value="#d#">#d#  <cfif #feed_date_d# is "d">selected</cfif></option>

                </cfloop>

              </select></th>

          </tr>
